First, install docker

Install docker on centos7. The official website has more detailed instructions:

Https://docs.docker.com/install/linux/docker-ce/centos/

The installation method I chose is Install from a package on the official website.

1. Docker requires that the kernel version of the CentOS system is higher than 3.10. Check the operating system version.

Uname-r

2. Download the rpm package of docker

Https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

Download the docker-ce-18.06.1.ce-3.el7.x86_64.rpm version

3. Delete the old version docker

Yum remove docker\ docker-client\ docker-client-latest\ docker-common\ docker-latest\ docker-latest-logrotate\ docker-logrotate\ docker-selinux\ docker-engine-selinux\ docker-engine

4. Add yum source

Sudo yum-config-manager\-- add-repo\ https://download.docker.com/linux/centos/docker-ce.repo

5. Installation

Yum install / opt/docker-ce-18.06.1.ce-3.el7.x86_64.rpm

6. Start the docker service and join boot startup

Systemctl start dockersystemctl enable docker

7. Check whether the installation is successful

Docker version

2. Start the docker private warehouse

1. Download registry

Docker pull registry

2. Start registry

Docker run-d-ti-- restart always-- name docker-registry-p 5000V / data/docker/registry:/var/lib/registry registry

3. Configure the address of private warehouse (all docker servers that need to be connected)

Vim / etc/docker/daemon.json

{"insecure-registries": ["xxx.xxx.xxx.xxx:5000"]}

4. Enable remote call (here is to generate docker image later using maven plug-in)

Vim / usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd-H tcp://0.0.0.0:2375-H unix://var/run/docker.sock
